Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The source is a browser workflow-compiler integration with no install hook or stealth behavior. Its network calls are tied to caller-supplied UiPath connection data and explicit tool operations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T14:30:16.428Z - **Finished:** 2026-09-07T14:31:01.237Z - **Download time:** 255 ms - **Static scan time:** 159 ms - **AI review time:** 44394 ms - **Total time:** 44809 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Authenticated remote compilation is activated only through explicit consumer registration and tool operations. - **Trigger:** A consumer registers the factory and invokes pack, validate, or cleanup with connection context. - **Impact:** Expected compilation-related network and output-file operations only. - **Review source:** ai\_review - **Reviewed:** 2026-09-07T14:31:01.237Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote UiPath job orchestration and result delivery. - **Rationale:** The source is a browser workflow-compiler integration with no install hook or stealth behavior. Its network calls are tied to caller-supplied UiPath connection data and explicit tool operations. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a library entry point and contains no lifecycle scripts., Runtime networking uses the caller-provided cloud URL and access token to create a UiPath job., The package only runs when a consumer explicitly registers its tool factory. - **Evidence against:** No install-time execution, shell commands, dynamic code execution, self-dependency, or credential harvesting was found., Network and file operations implement authenticated remote compilation and delivery of its output, not hidden exfiltration or persistence. ## Affected versions and remediation This report applies to @uipath/packager-tool-workflowcompiler-browser@1.201.0. - Review the evidence and your use of @uipath/packager-tool-workflowcompiler-browser@1.201.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 3. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 4. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** package.json - **Public source:** [View source]() The manifest exposes a library entry point and contains no lifecycle scripts. Public source snippet (untrusted): ```json "exports": { ".": { "source": "./src/index.ts", "default": "./dist/index.js" } } ``` ### 5. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** src/project-bundle-executor.ts - **Public source:** [View source]() Runtime networking uses the caller-provided cloud URL and access token to create a UiPath job. Public source snippet (untrusted): ```typescript const relativeBase = toRelativeUrl(connection.cloudUrl!); const onLocalRobot = context.jobTarget?.kind === PackJobTargetKind.LocalRobot; // Two different job-creation APIs, not one endpoint with a flag: the serverless // endpoint forces RuntimeType=Serverless and takes no machine targeting, while // BeginSession takes the runtime/machine fields but no jobType. The agent behaves // the same either way — it dispatches on Command in the input arguments. const url = onLocalRobot ? `${relativeBase}/orchestrator_/api/Rob ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** src/index.ts - **Public source:** [View source]() The package only runs when a consumer explicitly registers its tool factory. Public source snippet (untrusted): ```typescript // Workflow Compiler (browser) tool factory. Consumers register it explicitly via // `toolsFactoryRepository.registerProjectToolFactory(new WorkflowCompilerToolFactory())`. export { WorkflowCompilerToolFactory } from "./workflow-compiler-tool-factory.js"; ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 2 - **Development dependencies:** 0 - **Published dependency-graph edges:** 2 ### Published dependency entries - @microsoft/signalr \>=7 \<11 (PeerDependency) - @uipath/solutionpackager-tool-core 1.201.0 (PeerDependency) ## Package metadata - **Package:** @uipath/packager-tool-workflowcompiler-browser - **Ecosystem:** npm - **Version:** 1.201.0 - **License:** ISC - **Version published:** 2026-09-07T13:35:19.281Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-10-11T17:59:37.087Z - **Known versions:** 7 - **Latest version:** 1.203.0 - **Appeal under review:** No - **Description:** UiPath Workflow Compiler tool - browser implementation - **Maintainers:** qbrandon, mihhdu, toxik, sergiunet, vasyop, vnaren23, chibionos, ady\_mc, cristiancalina, ruud.andriessen, danboanta, andbalase - **Artifact files:** 34 - **Artifact unpacked size:** 174,361 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
